His invention greatly reduced the cost of steel production and fueled expansion in railroads, construction, and industry. Thomas Alva Edison: Edison held over 1,000 patents and is best known for inventing the phonograph, practical electric light bulb, and motion picture camera. He played a key role in developing electric power distribution and modern industrial research labs. Abraham Gesner: A Canadian geologist, Gesner invented kerosene in the 1840s as a cleaner, more efficient fuel for lamps. His innovation helped reduce reliance on whale oil and contributed to the growth of the petroleum industry. William Le Baron Jenney: Jenney was an architect and engineer who designed the first steel-framed skyscraper in 1884. His use of steel framing in construction revolutionized urban architecture and enabled the rise of modern cities.
